1. Write out the half-cell reaction for the oxidation of glucose-6-phosphate to ribulose-5- phosphate in the pentose phosphate pathway
Homework Answers
The pentose phosphate pathway is a metabolic pathway parallel to the metabolic pathway of glycolysis. It results in generation of NADPH and pentoses as well as ribose 5-phosphate, which is a precursor for the synthesis of Nucleotides.
The half-cell reaction for the oxidation in the pentose phosphate pathway is as follows :
Glucose 6-phosphate + 2 NADP+ + H2O → Ribulose 5-phosphate + 2 NADPH + 2 H+ + CO2

The first enzyme in the pentose phosphate pathway that oxidize glucose glucose-6-phosophate to 6- phosphoglucono-6-lactone is glucose-6-phosophate dehydrogenase. Deficiency of this enzyme causes health issues. Write 2-1 page description on the deficiency of the enzyme due to genetic mutations. (if this enzyme activity has completely diminished due to mutation, we cannot live). Include these terms in your writing and underline them whenever you use the terms.
